All global variables used by the Livecode World environment should be moved into a single namespace (a single global variable).
The handlers have a rough equivalent with regard to "library" handlers. The aim is to move over from one huge library, to individual projects. Each project would have it's own "home" stack, where we store stackfiles to all the stacks it needs to know about. Associated with this home stack we can use the standardised technique of logging metadata, where we can store arbitrary information. In this way the metadata of the projects home stack contains all the information we need about the project. For now let's keep using the old "library" rather than "project" based model for stackFiles. By this I mean we continue to store set array in the global library rather than in a folder associated with the project. The first stage of teh transition is to see if multiple home stacks with stackfiles works well. See also "meta_StackArrayFile" for project level stackfile storage
